Optimization of Pulsed Eddy Current Probes
, 1983 The objective of the ongoing work reported here is to optimize pulsed eddy current instrumentation for the detection of small flaws, specifically 250 × 125 pm crack-like defects in low conductivity materials such as titanium 6-4. Our approach parallels that employed in the optimization of continuous wave eddy current systems1,2 in that we seek first to

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Introduction/Objective Acute intracranial stenting during endovascular thrombectomy (EVT) for ischemic stroke requires intraprocedural antiplatelet therapy (APT) to maintain patency. However, the hemorrhagic risk of combining APT with intravenous thrombolysis (IVT) remains uncertain.

Flaws characterization with pulsed eddy currents NDT [PDF]
IEEE Transactions on Magnetics, 1999 In this paper, we present a method for characterizing flaws in metallic structures with pulsed eddy current nondestructive testing (NDT). In a first step, we explain why we have chosen a deconvolution method based on conjugate gradient algorithm (CG).
